White Clay Creek State Park
The land that is today known as White Clay Creek State Park includes parts of the boundary line made famous by Mason and Dixon, who began their historic survey at “a post mark’d west,” a location that lies within the park.
As overdevelopment in the northern part of the state became a matter of increasing concern in the late 1960s, the state began to purchase lands adjoining a small recreational park, which in 1975 became known as Walter S. Carpenter State Park. State land acquisitions and donations from the DuPont family and others eventually enlarged the park to over 3,600 acres. It was renamed White Clay Creek State Park in 1995. The White Clay Creek was named a National Wild and Scenic River by the National Park Service in 2000.
